From what I've read, for any location and particularly coastal locations, it means less normal weather and more and more extreme weather. For example, I know some areas that are getting less and less frequent snow days, but more and more frequent snowstorms. So average snowfall stays relatively above average but occurs only on a few days. (I.e., snows like three days all winter but 8-20 inches each time.)

So I would guess the answer to

> Dryer or more rainy season?

is yes.
